2020-04-27gdb, gdbserver: remove configure check for fs_base/gs_base in user_regs_structSimon Marchi5-71/+9
I recently stumbled on this code mentioning Linux kernel 2.6.25, and thought it could be time for some spring cleaning (newer GDBs probably don't need to supports 12-year old kernels). I then found that the "legacy" case is probably broken anyway, which gives an even better motivation for its removal. In short, this patch removes the configure checks that check if user_regs_struct contains the fs_base/gs_base fields and adjusts all uses of the HAVE_STRUCT_USER_REGS_STRUCT_{FS,GS}_BASE macros. The longer explanation/rationale follows. Apparently, Linux kernels since 2.6.25 (that's from 2008) have been reliably providing fs_base and gs_base as part of user_regs_struct. Commit df5d438e33d7 in the Linux kernel [1] seems related. This means that we can get these values by reading registers with PTRACE_GETREGS. Previously, these values were obtained using a separate PTRACE_ARCH_PRCTL ptrace call. First, I'm not even sure the configure check was really right in the first place. The user_regs_struct used by GDB comes from /usr/include/x86_64-linux-gnu/sys/user.h (or equivalent on other distros) and is provided by glibc. glibc has had the fs_base/gs_base fields in there for a very long time, at least since this commit from 2001 [2]. The Linux kernel also has its version of user_regs_struct, which I think was exported to user-space at some point. It included the fs_base/gs_base fields since at least this 2002 commit [3]. In any case, my conclusion is that the fields were there long before the aforementioned Linux kernel commit. The kernel commit didn't add these fields, it only made sure that they have reliable values when obtained with PTRACE_GETREGS. So, checking for the presence of the fs_base/gs_base fields in struct user_regs_struct doesn't sound like a good way of knowing if we can reliably get the fs_base/gs_base values from PTRACE_GETREGS. My guess is that if we were using that strategy on a < 2.6.25 kernel, things would not work correctly: - configure would find that the user_regs_struct has the fs_base/gs_base fields (which are probided by glibc anyway) - we would be reading the fs_base/gs_base values using PTRACE_GETREGS, for which the kernel would provide unreliable values Second, I have tried to see how things worked by forcing GDB to not use fs_base/gs_base from PTRACE_GETREGS (forcing it to use the "legacy" code, by configuring with ac_cv_member_struct_user_regs_struct_gs_base=no ac_cv_member_struct_user_regs_struct_fs_base=no Doing so breaks writing registers back to the inferior. For example, calling an inferior functions gives an internal error: (gdb) p malloc(10) /home/smarchi/src/binutils-gdb/gdb/i387-tdep.c:1408: internal-error: invalid i387 regnum 152 The relevant last frames where this error happens are: #8 0x0000563123d262fc in internal_error (file=0x563123e93fd8 "/home/smarchi/src/binutils-gdb/gdb/i387-tdep.c", line=1408, fmt=0x563123e94482 "invalid i387 regnum %d") at /home/smarchi/src/binutils-gdb/gdbsupport/errors.cc:55 #9 0x0000563123047d0d in i387_collect_xsave (regcache=0x5631269453f0, regnum=152, xsave=0x7ffd38402a20, gcore=0) at /home/smarchi/src/binutils-gdb/gdb/i387-tdep.c:1408 #10 0x0000563122c69e8a in amd64_collect_xsave (regcache=0x5631269453f0, regnum=152, xsave=0x7ffd38402a20, gcore=0) at /home/smarchi/src/binutils-gdb/gdb/amd64-tdep.c:3448 #11 0x0000563122c5e94c in amd64_linux_nat_target::store_registers (this=0x56312515fd10 <the_amd64_linux_nat_target>, regcache=0x5631269453f0, regnum=152) at /home/smarchi/src/binutils-gdb/gdb/amd64-linux-nat.c:335 #12 0x00005631234c8c80 in target_store_registers (regcache=0x5631269453f0, regno=152) at /home/smarchi/src/binutils-gdb/gdb/target.c:3485 #13 0x00005631232e8df7 in regcache::raw_write (this=0x5631269453f0, regnum=152, buf=0x56312759e468 "@\225\372\367\377\177") at /home/smarchi/src/binutils-gdb/gdb/regcache.c:765 #14 0x00005631232e8f0c in regcache::cooked_write (this=0x5631269453f0, regnum=152, buf=0x56312759e468 "@\225\372\367\377\177") at /home/smarchi/src/binutils-gdb/gdb/regcache.c:778 #15 0x00005631232e75ec in regcache::restore (this=0x5631269453f0, src=0x5631275eb130) at /home/smarchi/src/binutils-gdb/gdb/regcache.c:283 #16 0x0000563123083fc4 in infcall_suspend_state::restore (this=0x5631273ed930, gdbarch=0x56312718cf20, tp=0x5631270bca90, regcache=0x5631269453f0) at /home/smarchi/src/binutils-gdb/gdb/infrun.c:9103 #17 0x0000563123081eed in restore_infcall_suspend_state (inf_state=0x5631273ed930) at /home/smarchi/src/binutils-gdb/gdb/infrun.c:9151 The problem seems to be that amd64_linux_nat_target::store_registers calls amd64_native_gregset_supplies_p to know whether gregset provides fs_base. When !HAVE_STRUCT_USER_REGS_STRUCT_FS_BASE, amd64_native_gregset_supplies_p returns false. store_registers therefore assumes that it must be an "xstate" register. This is of course wrong, and that leads to the failed assertion when i387_collect_xsave doesn't recognize the register. amd64_linux_nat_target::store_registers could probably be fixed to handle this case, but I don't think it's worth it, given that it would only be to support very old kernels.

2020-04-16Fix Cygwin gdb buildTom Tromey2-0/+13
Simon pointed out that the windows-nat sharing series broke the Cygwin build. This patch fixes the problem, by moving the Cygwin-specific code to a new handler function.

This moves the wait_for_debug_event helper function to nat/windows-nat.c, and changes gdbserver to use it. wait_for_debug_event is a wrapper for WaitForDebugEvent that also sets last_wait_event when appropriate.

Both gdb and gdbserver have a "handle_exception" function, the bulk of which is shared between the two implementations.

This changes nat/windows-nat.h to declare handle_load_dll and handle_unload_dll.

This changes gdb and gdbserver to use the same calling convention for the "thread_rec" helper function. Fully merging these is difficult due to differences in how threads are managed by the enclosing applications; but sharing a declaration makes it possible for future shared code to call this method. gdb/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * windows-nat.c (enum thread_disposition_type): Move to nat/windows-nat.h.

This introduces a new file, nat/windows-nat.h, which holds the definition of windows_thread_info. This is now shared between gdb and gdbserver. Note that the two implementations different slightly. gdb had a couple of fields ("name" and "reload_context") that gdbserver did not; while gdbserver had one field ("base_context") that gdb did not, plus better comments.
